can i use my SD card as internal memorySupport

I wanted to save my internal memory and install new apps in external memory. Currently when i am doing so with app2sd the moved app uses some internal memory and the rest is transferred to external. Is it possible to transfer the entire installed app to External memory card..
I know there are some chances by creating a partition in memory card. But can anyone explain me how it is done..???

USE LINK2SD. PARTITION YOUR SD CARD USING MINI TOOL PARTITION TOOL WIZARD.
THIS APP WORKS ON ROOTED PHONE. IT HAS AN IN BUILT INTELLIGENCE AND TRANSFERS ALL THE ALL THE APPS AND THEIR DATA TO SD (INTERNAL ONE) AND KEEPS ON PHONE ONLY THE VERY NECESSARY ONE. ALSO IT GIVES YOU POWER TO MOOVES ANY APP, FREEZE, ETC. ITS BEST....... Android Micromax A73....
